Abstract

Six macroalgal species are reported as new or confirmed for the Aegean coasts of Greece (Eastern Mediterranean) thereby extending their distribution range: the brown alga Asperococcus ensiformis, and the red algae Chondria boryana, Dipterosiphonia dendritica, Gelidium pulchellum, Neosiphonia harveyi, and Taenioma nanum. Of particular interest are the findings of Gelidium pulchellum and N. harveyi which are described for the first time from the Eastern Mediterranean Sea; the latter species is considered as alien
in European seas. Description, illustrations, habitat, geographic distribution and taxonomical remarks are provided for each species. Our results indicate that the biodiversity of the Aegean Sea marine flora, and generally of the Eastern Mediterranean Sea, is probably richer than originally
thought.
